Abstract (en)

[origin: EP3586758A1] The invention provides a method for generating a transvalvular pressure quantification within a cavity. The method includes acquiring a plurality of color Doppler ultrasound image frames, wherein the image frames comprise a view of a valve, one of which is then presented to a user. The user may then provide an input to indicate the location of the valve within the image frame. The location of the valve is then tracked within the remaining image frames based on the user input. A vector flow is estimated based on the color Doppler image frames and the tracked location of the valve, which may be used to estimate the flow across the valve(s) and in the cavity.
